To all wlw/nt t may concern: y

Be it known that I, ALBERT J. EDDY, a citizen of the United States, anda resident of Long Branch, in the county of Monmouth and State of NewJersey, have invented a new and Improved Blowpipe- Torch, of which thefollowing is a full, clear, and exact description.

Among the principal objects which the present invention has in view areto provide means for preventing the boiling over of fluid liquid, orsuper-saturation of the supply wick therefor; to provide means formanually supplying the fuel to the wick; to provide a blow-pipe, theparts whereof are protected by the body structure of the torch; and toprovide simplified means for threading the wick in the torch structure.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in which- Figure 1 is aperspective view of a torch constructed and arranged in accordance withthe present invention; Fig. 2 is a vertical sect-ion taken on the line2-2 in Fig. 3; Fig. 3 is a top plan view yof the torch; and Fig. 4: is avertical section showing a modified form of the invention.

As seen in the drawings, the body portion of the torch is constructed inan oval shape, to form a flattened body adapted for transportation inthe pocket of the user.

The body is divided by a partition 9, to form a Huid-containing chamber10 and a wick-containing chamber 11. LThe chambers 10 and 11 havecommunication only through the orifices formed in a valve plug 12. Theplug 12 is bored to provide a sharply-tapered orifice or seat for aneedle-valve 13. The stem of the valve 13 is provided with ascrew-threaded section 14, the threadswhereof register with threadsformed in the end of a tube 15. The tube 15 is furnished with sideopenings 16, said openings forming a communication with the chamber 11.

The tube 15 is structurally connected with the partition 9 and thebottom 17. The tube has structurally mounted therein the plug 12 and aplug 18, the former, as above stated, forming a valve-seat for the valve13, and the latter forming a guide for the stem of the said valve, itbeing bored to provide a passage for said stem. The openings 16. are

located' above the plug 18, as seen best in i Fig. 2 of drawings. Theplug 18 in this manner serves to `obstruct the opening through the tube15, and to divert the fluid into theV chamber 11 whenthe valve 13 isremoved from its seat in the plug 12. To manipulate the valve 13, thestem is provided with a milled nut 19. It will be noted that the nut 19is` raised above the lower edge of the body casing of the torch, 4thebottom 17 being removed from the lower edge to provide a recess for thenuts 19 and 20.

The lower end of the wick 421 is packed in the chamber 11, the strandsthereof being wrapped about the tube 15 in the manner shown best in Fig.2, and about the lower end of a tube 22. It will be noted that the tube22 and the opening in the bottom 17, which is normally closed by themilled nut 20, arein line, which arrangement facilitates the threadingof the wick 21 through the tube 22. In placing the wick in the torch,the end of the wick is passed through the opening in the-bottom 17closed by the nut 20, and into and through the tube'22, until the end ofthe wick is raised above the end of said tube, where the 4same protrudesabove the top 23 of the body of the torch.

The exposed end of the wick is normally covered by a cap 24, said caphaving a screw-threaded section, the threads whereof register withthreads formed on the exposed end of the tube 22. When the wick is thusadjusted in the tube 22, the'surplus or free` end thereof is packedthrough the opening in the bottom 17, and arranged therein in the mannershown in the drawings, any convenient. device or tool being used for.packing the same. After the l'ower end of the wick is thus packed, themilled nut 20 is adjusted to'position and tightly secured therein, toprevent any leakage of free fuel fromv the chamber 11. I

The fuel usually employed in torches .offclO this class is alcohol. Thesupply is normally carried in the chamber 10, and is introduced thereinthrough an opening in the top 23, normally closed by a milled nut 25.Each of the nuts 19, 20 and 25 is provided-with a washer 26. The washers26 are constructed of Vany suitable material adapted 'for the particularservice to which they arel applied. Thev principal service in which thetorch v is employed is for soldering or heating'. mate- :110V

rials upon which the mechanic is at work. To direct the flame, and toaugment the same, a blow-pipe 27 is provided. In the present instance,the blow-pipe 27 is extended through the chamber 10, and is providedwith two exposed ends 23 and 29. Both ends are held as close to the bodystructure of the torch as possible, to avoid damage by being struck orpressed upon by lo extraneous objects or obstacles.

To the end 28 is usually connected a rubber pipe 30, which is used as amouthpiece by the mechanic to direct a stream of air through the pipe 27and the orifice 31 formed in the side of the end 29 adjacent and facingthe exposed end of the tube 22. The end 29 is closed above the orifice31. It will be noted that when the cap 24 is mounted in position, asseen best in Figs. Y2 and 3 of drawings, the end 29 is fairly protectedfrom being injuriously struck or bent.

In the operation of the invention as above described, the wick 21, beingin position, is primed or saturated with alcohol from the chamber 10, bymanipulating the nut 19, to move the valve 13 from the seat in the plug12. The alcohol then flows through the tube 15 and the opening 16, tothe wick 11, saturating the same, and being carried by capillaryattraction to that portion of the wick which is in the tube 22, untilthe entire wick, up to and including the tufted end under the cap 24, ispermeated with the alcohol.

When the wick has become sufficiently saturated, the nut 19 ismanipulated to close the valve 13 on its seat, and to thereby preventthe flow of alcohol from the chamber 10 to the chamber 11. rThe cap 24is now re moved, and a flame is applied to the tufted or exposed end ofthe wick. In the employment of t-he torch, the mechanic, by placing thefree end of the rubber pipe 30 in his mouth, causes a steady draft ofair trans verse the flame from the wick 21, drawing said flame, as in ablow-pipe, to a pencil or point. When, in the course of operation, theHame indicates that the wick 21 requires an additional supply of fuel,this is accomplished by removing the valve 13, to allow a supply ofalcohol in'the chamber 10 to pass into the chamber 11. After eachmanipulation of the valve 13 to permit the flow of fuel from one chamberto the other, the valve is closed, the purpose of the presentconstruction being to avoid the o-ver-supply of fuel due to theexpansion caused by the heat of the fiame in the chamber 10, to forcethe fuel through the wick 21 faster than the same is consumed by theiiame, resulting` in the so-called boiling over or fluffing off offlaming portions of the fuel.

`In the modified form shown in Fig. 4: of drawings, the tube 15 andvalve 13 and parts connected therewith are dispensed with, and

Y substituted therefor is a disk valve 32, at

the lower side of which is provided a tapered spur 33. The spur fitswithin, to close, an orifice formed in the partition 9, which orifice issubstituted for the seat in the valve plug 12 of the preferredconstruction, above described. In the modified form, the disk valve 32is normally maintained in seated relation by a spring To unseat the diskvalve 32 to permit the transfer of the fuel from the chamber 10 to thechamber 11, there is attached to the disk valve 32, by means of aneyelet 35, a chain 36. The chain 3G is furnished with a swivel eyelet38. as seen in F ig. ll. The eyelet 38 is secured pivotally in positionupon a screw cap 39, the threads whereof register with threads formed onthe extension 37. When using the modified form of the invention, theoperation varies only in that, to renew the supply of fuel to thechamber 11, and the wick 21 contained therein, the cap 39 is removed,and the chain 3G connected therewith is raised until the disk valve 32is lifted to expose the orifice normally closed by the spur 33. lVhenthe chain 3G is released., the spring 34 re-seats the disk valve 32, toclose and maintain closed, said orifice.

It will be noted that any pressure due to expansion of the fluid in thechamber 10 operates to seat the disk valve 32 in closure position abovethe orifice in the partition 9.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A torch such as described, having an ellipticaltubular body, a partition intermediate the ends of said body to form insuperposed relation a liquid fuel storage chamber and a wick storagechamber, a manually controlled valve mounted in said partition totransfer the fuel from the fuel storage chamber to the wick storagechamber, and a wick guide tube extending completely through said fuelstorage chamber and opening into said wick storage chamber and beyondthe end of said body to provide radiating surface within said fuelstorage chamber.
